The Kubernetes Workshop

By: Zachary Arnold, Sahil Dua, Wei Huang, Faisal Masood, Mélony Qin, Mohammed Abu Taleb

Overview of this book

Thanks to its extensive support for managing hundreds of containers that run cloud-native applications, Kubernetes is the most popular open source container orchestration platform that makes cluster management easy. This workshop adopts a practical approach to get you acquainted with the Kubernetes environment and its applications. Starting with an introduction to the fundamentals of Kubernetes, you’ll install and set up your Kubernetes environment. You’ll understand how to write YAML files and deploy your first simple web application container using Pod. You’ll then assign human-friendly names to Pods, explore various Kubernetes entities and functions, and discover when to use them. As you work through the chapters, this Kubernetes book will show you how you can make full-scale use of Kubernetes by applying a variety of techniques for designing components and deploying clusters. You’ll also get to grips with security policies for limiting access to certain functions inside the cluster. Toward the end of the book, you’ll get a rundown of Kubernetes advanced features for building your own controller and upgrading to a Kubernetes cluster without downtime. By the end of this workshop, you’ll be able to manage containers and run cloud-based applications efficiently using Kubernetes.

Preface

Terraform

In the last chapter, we used kops to create a Kubernetes cluster from scratch. However, this process can be viewed as tedious and difficult to replicate, which creates a high probability of misconfiguration, resulting in unexpected events at application runtime. Luckily, there is a very powerful community-supported tool that solves this issue very well for Kubernetes clusters running on Amazon Web Services (AWS), as well as several other cloud platforms, such as Azure, Google Cloud Platform (GCP), and many more.

Terraform is a general-purpose infrastructure life cycle management tool; that is, Terraform can manage the state of your infrastructure as defined through code. The goal of Terraform, when it was initially created, was to create both a language (HashiCorp Configuration Language (HCL)) and runtime that can create infrastructure in a repeatable manner and control changes to that infrastructure in the same way that we control changes to application source code—...
